Humans did not exist back then smart arse. At least for a while we would linger afterward unless all the oxygen is gone. Which in the movie is probably about too anyway as there is no more plant life producing oxygen anymore. The algae they consume uses Chemosynthesis as opposed to Photosynthesis because there is virtually no sunlight that reaches the planet's surface anymore.

If the rate was really that accelerated we would already have seen over half of all flora and fauna of the Earth gone and we would already be needing exopacks to just breathe, the sky would not even be blue anymore.

Nobody but nobody has come up with a feasible scientific proof that what we see in the movie could take in just 100 years or even less as you now claim. Again I am not saying that it cannot happen but that the rate you now claim which surpasses that of the movie is pretty skewed and has no scientific basis. And again keep in mind that unlike the movie people are switching to renewable resources and so on. As you well put it the third overpopulation is unsustainable of itself. Also when it comes to really dumb people even with all the advances we have they somehow always manage to kill themselves sooner or latter you really should check out the TV show 1000 ways to die from Spike.
